Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):

From: Lars Ingebrigtsen <larsi <at> gnus.org>

Subject: 24.0.92; No png images on OpenSUSE 12.1
Date: Sun, 22 Jan 2012 17:12:18 +0100

I'm trying to compile Emacs 24 (current bzr) under OpenSUSE 12.1.
Everything seems to work fine except inserting PNG images.

If I do the following, I just get a blank square:

(insert-image (create-image "/music/repository/Arto Lindsay/Prize/thumbnail.png"))
t

If I insert a gif or a jpeg, things work fine.  If I try to insert
something that isn't an image at all, I get an error message.  But with
pngs, I don't get any error messages, and I don't get an image, just
that blank square.

The png libraries seem to exist:

larsi <at> linux-hvfx:~/src/emacs/trunk> ldd src/emacs | grep png
	libpng12.so.0 => /usr/lib/libpng12.so.0 (0xb7631000)
	libpng14.so.14 => /usr/lib/libpng14.so.14 (0xb656f000)
larsi <at> linux-hvfx:~/src/emacs/trunk> ls -l /usr/lib/libpng12.so.0 /usr/lib/libpng14.so.14
lrwxrwxrwx 1 root root 18 Dec  8 01:20 /usr/lib/libpng12.so.0 -> libpng12.so.0.46.0
lrwxrwxrwx 1 root root 18 Nov 10 17:25 /usr/lib/libpng14.so.14 -> libpng14.so.14.8.0

Is there any way to get more image debugging switched on?
